To find the types of sentiment among users, we conducted an interactive process of coding.
In this process, three authors of this paper first discussed the initial coding guide from previous work [1]}.
To make the coding guide fit with our study, the initial coding guides were adjusted.
We (first, second, and sixth authors) then independently applied the adjusted coding rules on both initial posts and the first responses of the first 30 samples of thread.
We used the kappa score calculator to check the agreement level and find the score 0.78. REF
According to [2]}, this kappa agreement score is `acceptable'.
Based on the agreement level, the coding tasks for the remaining threads from samples were undertaken by the three authors, which each author classified 383 different samples of threads.
